Moonboy here speaking: Patience is key and I'm sure other initial believers in crypto will tell you the same, it's not so much the profits (it's really nice side effect though

) but more of what these coins can do for society.
Get in now or get in later, either way the train doesn't seem to be stopping. Sure a few rest stops along the way, but it's still going.
The guys from crypto wave 1 (2010-2012) had a chance to become billionaires today.
The guys from crypto wave 2 (2013-2017) had a chance to become millionaires today.
We're currently in crypto wave 3 now, and the guys from waves 1 & 2 are up-scaling to trillionaires and billionaires over the next 5 years.
Someone getting into crypto today can still make good money, but most will lose it all, the golden age is over.
